By tin, do you mean that faux ceiling tile stuff that was popular several years ago? Tiling around outlets and switches is really not that bad even as a DIY job.

Try it...... Comments from this photo:

Have you looked into rust/water issues? A very easy DIY is using stainless steel tiles and I believe for a charge Home Depot can cut for your outlets, etc. We have used the larger subways behind our stove and love it (resembles below) and they came with a pealable back. No matter what you select, make sure it will look ok if you only go partially up, as it may feel very unfinished (couldn't find one picture).

I have seen tin backsplashes melted behind gas stoves, so be cautious about where you are placing this. While I have never specified a kitchen tile backsplash only partially up on the wall, if you do this make sure to have it look intentional. Such as having it follow the height of where maybe the sink window cuts the backsplash off. Also use a trim piece; a pencil tile or some type of architectural tile to cap the top. Best of luck in your selections and installation.

Have you decided on something or already done it? We'd love to see! American Tin Ceilings has tin backsplash tiles that are designed for this kind of treatment (including behind a stove and pass code for fire/heat resistance) and use a J trim to give the finished look. We are doing this behind our stove in our remodel.
